AI coding assistants are no longer optional. Most developers use at least one daily. But the three leading options take very different approaches.
Cursor is a VS Code fork with AI built into the editor. Windsurf is Codeium's standalone IDE. Claude Code is a CLI agent that runs in your terminal.
This guide covers what each tool does, how they compare on features and pricing, and which one fits your workflow.

What each tool does
Claude Code
A terminal-native AI agent from Anthropic. You run it inside your project directory and it reads, writes, and executes code directly in your shell. No IDE required.
Claude Code understands your full repo. It can grep across thousands of files, run tests, commit changes, and manage git workflows. It uses MCP servers to connect to external tools like GitHub, Supabase, and Slack.
Best for developers who live in the terminal and want an agent that operates at the system level, not just inside a file.
Cursor
A fork of VS Code with AI deeply integrated. Tab completion, inline editing, chat, and multi-file editing all work inside the editor. Your existing VS Code extensions and settings carry over.
Cursor supports multiple models: Claude, GPT-4o, and its own fine-tuned models. You can switch between them per task. It added MCP support in late 2025 and has a growing plugin ecosystem.
Best for developers who want AI integrated directly into their IDE with visual diff previews and inline suggestions.
Windsurf
Codeium's AI-native IDE, previously known as Codeium Editor. It uses a "Cascade" agent that can make multi-file changes and run terminal commands. The interface is similar to VS Code but built from scratch for AI workflows.
Windsurf focuses on "flow state" coding. It predicts your next action and suggests edits across files. MCP support was added in early 2026.
Best for developers who want a lighter IDE alternative to Cursor with strong autocomplete and a clean interface.
Feature comparison
| Feature | Claude Code | Cursor | Windsurf |
|---|---|---|---|
| Interface | Terminal / CLI | IDE (VS Code fork) | IDE (standalone) |
| MCP support | Native, deep integration | Supported since late 2025 | Supported since early 2026 |
| Skills / plugins | CLAUDE.md + custom skills | .cursorrules + VS Code extensions | .windsurfrules + limited plugins |
| Hooks / automation | Pre/post command hooks | Via VS Code tasks | Limited |
| Terminal access | Full (runs in terminal) | Integrated terminal | Integrated terminal |
| Multi-file editing | Yes, across full repo | Yes, with visual diffs | Yes, via Cascade agent |
| AI models | Claude only | Claude, GPT-4o, custom | Claude, GPT-4o, Codeium |
| Tab completion | No (agent-based) | Yes, very fast | Yes, good quality |
| Git integration | Full CLI git workflows | VS Code git panel | Basic git panel |
When to use each one
Use Claude Code if you:
- Prefer working in the terminal over a GUI
- Need an agent that can run builds, tests, and deploy scripts
- Work across large monorepos or multiple projects
- Want deep MCP server integration for tools like GitHub, Supabase, and Slack
- Use CLAUDE.md files to give context about your codebase
Use Cursor if you:
- Want AI inside your editor with inline suggestions and diffs
- Rely on VS Code extensions and keyboard shortcuts
- Need fast tab completion while typing code
- Want to switch between AI models depending on the task
- Prefer visual code review before accepting changes
Use Windsurf if you:
- Want a cleaner, lighter alternative to Cursor
- Like the Cascade agent's predictive editing approach
- Don't need deep VS Code extension compatibility
- Want solid autocomplete without paying Cursor prices
Many developers combine tools. A common setup: Cursor for daily coding with Claude Code running in a terminal for larger tasks like refactoring, debugging, or deploying.
MCP server support across tools
The Model Context Protocol lets AI tools connect to external services. All three tools support MCP, but the depth varies.
| MCP feature | Claude Code | Cursor | Windsurf |
|---|---|---|---|
| Config file | .claude/settings.json | .cursor/mcp.json | ~/.codeium/windsurf/mcp_config.json |
| Server types | stdio + SSE | stdio + SSE | stdio |
| Approval flow | Allowlist in settings | Per-action approval | Per-action approval |
| Project-scoped config | Yes | Yes | Global only |
Claude Code has the most mature MCP integration. Anthropic created both the protocol and the tool, so they evolve together. For a full list of compatible servers, check our best MCP servers in 2026 guide or browse the MCP directory with 2,500+ servers.
Skills and extensions ecosystem
Each tool has its own way of extending functionality beyond the base AI features.
Claude Code: skills and CLAUDE.md
Claude Code uses markdown files for configuration. A CLAUDE.md file in your repo root gives the agent context about your project: tech stack, coding conventions, deployment steps. Skills are reusable instruction sets you can invoke with slash commands.
Browse 2,000+ skills in our skills directory or read our guide on the best Claude Code skills.
Cursor: rules and extensions
Cursor uses .cursorrules files for project context, similar to CLAUDE.md. It also supports all VS Code extensions, which gives it the largest plugin ecosystem of the three. The Cursor-specific marketplace is growing but still smaller than VS Code's.
Windsurf: rules and Cascade
Windsurf uses .windsurfrules for project instructions. Its extension ecosystem is the smallest of the three. The Cascade agent is the main differentiator: it chains multiple actions together and predicts what you want to do next.
Pricing comparison
| Plan | Claude Code | Cursor | Windsurf |
|---|---|---|---|
| Free tier | No | Limited (2 weeks trial) | Yes, with limits |
| Individual | $20/mo (Claude Pro) | $20/mo (Pro) | $15/mo (Pro) |
| Team | $30/mo per seat | $40/mo per seat | $35/mo per seat |
| Usage model | Token-based limits | Request-based limits | Credit-based |
Windsurf is the cheapest option for individuals. Cursor and Claude Code cost the same at $20/month. For teams, Claude Code is the most affordable per seat.
All three charge differently for overages. Claude Code uses token limits. Cursor counts "fast" requests with a monthly cap. Windsurf uses a credit system where different actions cost different amounts.

Browse MCP serversFrequently asked questions
Can I use Cursor and Claude Code together?
Yes. Many developers use Cursor as their IDE and Claude Code in a separate terminal for tasks like refactoring across files, running builds, or managing git workflows. They complement each other well.
Which tool has the best MCP server support?
Claude Code has the deepest MCP integration. It was built by Anthropic, who created the MCP protocol. Cursor added MCP support in late 2025 and it works well. Windsurf supports MCP but the ecosystem is smaller.
Is Claude Code free?
Claude Code requires a Claude Pro ($20/month) or Team ($30/month) subscription. It is included in those plans with usage limits. There is no separate Claude Code subscription.
Which tool is best for large codebases?
Claude Code handles large repos well because it works at the terminal level and can grep, read, and navigate files without loading everything into an IDE. Cursor works best when you open specific folders. Windsurf is similar to Cursor in this regard.
